How can I reduce standby power use in my home?Limited research suggests that an informed and aggressive approach can reduce standby use by about 30%. Frankly, there are more productive ways to save energy with an investment of an hour but if high standby energy use stands between you and the goal of a zero energy home, then it's an hour well spent.
How much power is used for standby in the US?...Worldwide?
Nobody knows for sure, but it's typically 5-10% of residential electricity use in most developed countries...
So if you're willing to waste a lot of your time and effort you might be able to shave your electrical use by 1.5% to 3%. I'd rather skip buying a morning coffee one day a month.
